  • Mapping information stored in a LDAP tree structure to a relational database structure
    Patent number: 9361346
    Abstract: A method for mapping an information directory such as a LDAP directory tree to a relational database structure. The method includes accessing an information directory, which has a number of data entries at nodes of its tree structure and each of these entries may include a number of attributes defined by one or more object classes. The method includes storing a distinguished name (DN2ID) index table including generating records the data entries that include a DN field containing the entry's attributes. The method includes forming a relational table associated with each of the object classes defined for the information directory, and the records of the relational tables may be linked to the records/entries of the DN2ID index table. The method may include determining an entry identifier for each of the entries of the directory and storing these in the records of the DN2ID index table and in the relational tables.
